To all whom it may concern:

Be it known that I, CLIFFORD SHAW, hydraulic engineer, of No. 100Broadway, in the city and State of New York, have invented certain newand useful Improvements in Apparatus for Lifting Water, of which thefollowing is a specification.

One way of lifting water has been'to deliver the water into a reservoirwell or pit in which the water-lif ting mechanism is placed. 'Where thesystem known as the Bacon air-lift is employed for raising water, thereservoir well or pit will have a depth proportionate to the height towhich the water is to be raised, as will be understood by every oneskilled in the art. Where such reservoir-wells are used for liftingwater or other liquids that contain sediment, there is always danger ofthe mechanism becoming so clogged when out of use that it will not startagain properly.

The object of the present invention is to provide means for preventingthe excessive settling of sediment in or around the waterliftingmechanism. This object I attain by entirely inclosing the lower portionsof the apparatus when out of useas, for example, by gates or valveswhich either close the mouth of the well or close the well farther down,near the intake-mouth of the air-lift mechanism employed.

In the preferred forms of the invention an air-lift is employed, and thevalve or gate should be placed so far above the intake-opening of theuptake-pipe that any sediment that may have accumulated above the valveor gate will not clog the mechanism when the valve or gate is againopened. As a matter of convenience I prefer to place the valve or gateeither just beneath the lowest level at which the water stands in thewell or else (where the upper part of the pit is a comparatively largereservoir having an eight or ten inch immersion-Weller smaller pitextending downward to give the necessary depth of immersion) at the headof the immersion pit or well.

In my application, Serial No. 9,696, filed March 22, 1900, I have setforth my invention broadly in manyof its preferred forms. This presentpatent application is a division of the earlier one for the purpose ofspecifically claiming a different form of the invention from thatclaimed specifically in the earlier one.

Figure 1 is a sectional view of one form of the invention. Fig. 2 showsa modification.

In Fig. 1 the large part of the'reservoir or pit is shown at b; but thismay also be understood as illustrating a shaft in a mine or, indeed, anyopen space, because the immersion pit or well proper is at c. Theuptakepipe for the air and Water is shown at d and the air-pipe at c. Ihave shown the air-pipe e surrounding the uptake-pipe; but it is notnecessary that either pipe should be within the other. At h is avalve-seat with which the valvej cooperates. The water or other liquidflows into the well 0 through the valveseat 71 when the'valve is open.The valvej is mounted to slide up and down upon a rod tor otherconnection that is provided for raising the valve. The operation of thisform of the invention is as follows: When the well is in use that is tosay, is operatingthe valve j is open, as in the figure. The water orother liquid passes through the open valve and down into theimmersion-well c, and thence up through the uptake 61. The screen anserves to prevent logs or other obstructions from getting into the valveand Well 0. When the apparatus is stopped and the air shut off, thevalve j is lowered into place and may so remain until the operation isresumed. When the well is not in operation, only the sediment within thewell 0 and beneath the valve can settle down about the inlet-openings inthe pipes d and c. Any mud or other sediment settling from the waterabove the valve j is of course prevented from entering the well a. Whenthe operation is again resumed, the rapid flow of water through thevalve j carries with it some of the sediment that has settled above thevalve; but this does no harm when the well is in operation, as it cannotsettle.

In Fig. 2 the valve 7' is adapted to be raised and lowered or maintainedopen by levers u. and an adj usting-screw o, which operates upon ascrew-threading nut r to raise and lower one end of the lever a, asshown, and slide the valve vertically on the pipe 6.

In both forms of the-invention the valve may be guided in its movementssolely by the air-lift mechanism, and, on the other hand, the conicalvalve, in conjunction with its seat, acts to center the air-liftmechanism in the well.

I claim as novel, in addition to and as a division of my said otherapplication, the following:

1. In combination in apparatus for raising liquid of the type employinga subniergence pit or well and an air-lift mechanism, a valveseatthrough which liquid is admitted to the air lift mechanism, and a valvetherefor mounted and movable upon the air-lift mechanism, substantiallyas set forth.

2. In combination in apparatus for raising liquid of the type employinga submergence pit or well and an air-lift mechanism, a valveseat throughwhich liquid is admitted to the air-lift mechanism, and a valve guidedby but controlled independently of the air-lift mechanism, substantiallyas set forth.

In combination in apparatus for raising liquid of the type employing asubmergence pit or well and an air-lift mechanism, a valveseat throughwhich liquid is admitted to the air-lift mechanism, a valve encirclingand sliding .upon the air lift mechanism and means for moving the valve,substantially as set forth.

4. In combination in apparatus for raising water wherein the water to beraised is first delivered into a reservoir well or pit, air-liftmechanism for raising the water from the said well or pit, and a valvethrough which the air mechanism extends, independently movable forcontrolling the delivery of water thereto, substantially as set forth.

5. In combination in apparatus for raising Water, wherein the water tobe raised is first delivered into a reservoir well or pit, air-liftmechanism for raising the Water from the well or pit, combining anuptake and a downtake pipe one within the other, a valve mounted toslide parallel with and upon the outer pipe, a valve-seat thereforthrough which the water passes to the well or pit, and means for movingthe said valve to open and close the well or pit, substantially as setforth.

6. In combination in apparatus for raising water, wherein the Water tobe raised is first delivered into a reser voir well or pit, air-liftmechanism for raising the Water from the Well or pit, combining anuptake and a down take pipe one within the other, a valve encircling theouter pipe and movable relatively thereto, a valve-seat therefor throughwhich the water passes to the well or pit, and means for raising,lowering, and supporting the said valve, substantially as set forth.
